0.37.06 appears to de-interlace European Blu-ray 1080i50 sources to 1080p25 if the "Use Decomb" box is ticked (if one is to believe MediaInfo). If we stick to standards, this should not happen as 1080p25 is not in the BD standard.While the decomb deinterlacing option will make the picture "progressive" in nature, it should still be flagged as interlaced for compatibility with BD standards via the "--fake-interlaced" encoding option of X264. I'll check it out and make sure it is working correctly.
[Edit] I just checked the code. "--fake-interlaced" is used for all deinterlaced encodes. So either X264 is incorrectly flagging it or your reporting software is incorrect. I would tend to believe the latter.
The only other possibility would be if your original was 1080p25 -- as BD-RB wouldn't change that.
Can you run it again and see if "--fake-interlaced' is used in the command line?

Not currently.
Thanks, but is it something for a future release, or not really?
I guess that is the chance you take when importing BD's LOL.

JDobbs, I posted the inf and log of a compression of "Amarcord" a few days ago where I ended up with an out of sync audio delay of almost 2 seconds. This was the only one affected using the most recent build of your program. All others compressed with that build don't have the problem.
Is there any way I can correct it?

Another "ReencodeAudio() 00075 1801" error, this time on Charles Ferguson's Inside Job. VID_00022 (1,00 MB) has one LPCM audio track which whacks the audio re-encoding module upside the head.

I checked, it's not. 1080p25 Blu-rays don't exist, AFAIK. Or did you mean 1080p25 fake-interlaced as 1080i50 on disc?

Will do!
[Edit] Yes, it is:

I'll burn the output to BD-RE to see how stand-alones react to it.

Either the file has disappeared, it is corrupt, or you don't have privileges to access it. Make sure the path to your working folder is legal. The error is most likely happening when attempting to create the .BAT file that does the actual audio encoding.

I'll burn the output to BD-RE to see how stand-alones react to it. Then the file is completely legal. I'm guessing Mediainfo is not looking at the proper flags that are set by "--fake-interlaced". The only other possiblity is if that option stopped working in X264 and that's an extremely low probability.

I'm trying to back up Fight Club to BD25, and I'm doing a little tweaking to the audio selections, which are being changed by merely collapsing/expanding other selections in the stream tab.
My relevant(?) audio options in setup are thus:
Audio Languages to keep: English (eng).
Limit to one track for each language: NOT checked.
Do not convert DTS to AC3 is CHECKED.
Do not reencode AC3 is CHECKED.
Use 448/192 Kbps are both NOT checked.
Keep HD audio for BD25 is CHECKED.
The only real change I ended up making was to the main movie m2ts, and I chose to drop the AC3 version of the standard (non-commentary) audio track completely, in that it's utterly superfluous, since the DTS HD MA track contains a DTS core, which all players are mandated to decode. I manually deselected this track, then continued on to expand and sometimes recollapse the audio and video track trees for each of the many m2ts files below, checking for additional superfluous tracks (I gave up, this BD is a mess). Once I scrolled back up to review, my manual deselection had been overriden and the primary ac3 track was again set to be included in the rebuild.
To test, I manually deselected it again, scrolled to the very last m2ts, collapsed and reexpanded everything therein, and scrolled back up, and the track had been selected for inclusion again.
I didn't enter into the setup menu at all during the above process (as I know this can change selections/deselections) but after all this, I did close BD-RB and reopen it, then attempt to reproduce the problem, and now it isn't happening, so it's not consistent.
EDIT:
OK, I just figured it out, after typing up that huge mess.
Any time you have a stream highlighted, if you double-click in the white-space of the stream tab, most anywhere (but not quite everywhere) that doesn't trigger any other UI component, it will toggle selection for the highlighted stream, even if you've scrolled well beyond it and can't see it. This behavior is consistent, but some whitespaces trigger it while others don't.

One thing to watch is streams that are linked as parts of an overall playlist (marked with asterisks). If you deselect or select audio on any of the linked streams it will change it for all of them.

BD_Rebuilder was changed recently to disable sleep mode while it was running. I believe it remains disabled even after the rebuild(s) is/are complete. Is it possible to re-enable it afterward?
Any response?
jdobbs
25th March 2011, 19:15
Any response? It is supposed to already be reenabled afterward. I'll look at the code to be sure it is doing so.
Also please review the first post of this thread which says:If you decide to download and test -- please post any errors you find in this thread. Don't push bug resolution or keep asking for a fix. I will get to the reported bugs, but only when I can find the time.
[Edit] I just checked, and it is doing the settings appropriately. Sleep is enabled -- but because of the way the microsoft interface works, the clock starts over at the point the encode is complete. So, for example, if you have the sleep timer set for 1 hour -- the system will go to sleep one hour after the encode is completed.

Anyhoo, with "Use Decomb" box unticked, the UK 1080i50 source came out as 1080/25 MBAFF, says Mediainfo.

Sorry to have caused confusion by interfering.
I just double checked a former --fake-interlaced encode with latest MediaInfo. It reports it correctly as "interlaced=fake"....

Yep, but this m2ts was the only thing in its playlist. I quickly edited my post instead of replying to myself, and might have caused you to miss where I mentioned I think I found what's causing it: any time a stream is highlighted, and you double-click certain parts of the white-space of the stream tab (most any part that won't trigger any UI components), it toggles the highlighted selection on/off, even if it's off-screen due to scrolling.

This disc is from the Criterion Collection and there appears to be nothing out of the usual. In fact I just compressed the full disc of "Black Orpheus" which is on the Criterion label as well.
I have another problem/question which is unrelated. I generally don't have a desire to compress audio but whenever I have tried, I get this error - ERROR in attempt to reencode audio (AFTEN) [AUD_00237__4352.AVS]
[16:32:23] - Failed to reencode audio, aborted.
FWIW, in this case the only box checked in the Audio encoding options would be (use 448kbs for AC3 encoding) Though I realize I don't have much of a clue how those settings work. My hope was to down sample a LPCM mono 1152kbps audio track to save some space and leave other 192 kbps tracks unchanged, if that is possible.

I sent above message as I was getting this, since that being sent and your reply,I removed the programs and reinstalled them a couple of times without success,after the last install I went to Watch the England match on TV after it was over I returned to the program to find it works perfectly,I can only assume that in the downloads somewhere a corruption occured. Thanks for your very fast reply to a 70 year old in trouble, its good to know the elderly can still get fast assistance. GREAT PROGRAM AND LONG MAY YOU CONTINUE!!!!!!!!!!!!

Then it shouldn't even be reencoding when your output is to BD-25. I'd have to guess that you have reset MIN_M2TS_SIZE to "0". If so I'd recommend you set it to something more reasonable. I guess it's possible that it could be a part of a larger playlist?

1440x1080p24 and 1440x1080p23.976 are both allowed by the BD specs. I'm not going to argue whether they're "full HD" as that's mere marketing gibberish, but they are allowed, and titles that use them are bound to exist.

What if the source were 1440x1080 anamorphic 16:9?
Then --sar 4:3 should probably be added to the x264 command line in order to stretch it correctly during playback.
I am not sure if 960x720 is blu-ray compliant.
Edit: If however 1440x1080 anamorphic 16:9 gets resized to 1280x720 then --sar 1:1 is perfect and everything is blu-ray compliant

What if the source were 1440x1080 anamorphic 16:9?
I've heard people say that before. But I think it's a misconception. 1440x1080 is not allowable in 16:9 (at least the way I read the spec). It seems to be meant only for 4:3. The BD Spec (under primary video plane parameters, table 8-4, note 2) says:The 1440 samples shall be converted to its 1920 samples by using the 4/3 interpolation filter, and the 1920 samples are presented on the Video plane.
It also says under the description of 1920x1080 format (there isn't a section defining 1440x1080 because it is a subset of 1920x1080):The 1440 samples are derived from the 3/4 decimation filtering the 1920 samples.The shall means that there are no exceptions. And of course this means that the 1440x1080 source would also be a 1:1 aspect display ratio. If you are using a 1440 source that has been flagged as 16:9, you might indeed get a "stretched" picture -- but the fault would be in the illegal source, not BD Rebuilder.
1440x1080p24 and 1440x1080p23.976 are both allowed by the BD specs. I'm not going to argue whether they're "full HD" as that's mere marketing gibberish, but they are allowed, and titles that use them are bound to exist. But not at 16:9 from what I can see.
A.Fenderson
28th March 2011, 20:49
I don't have access to authoritative sources, and I don't wish to argue, but the quote you used and cited as being the BD spec pretty much means exactly the opposite to me what it does to you: it says the 1440 samples are converted to 1920 via 4:3 interpolation--if the pixels were 1:1, there would be no interpolation, simply the addition of pillarboxing on the sides to maintain the 4:3 Picture aspect ratio of the original.

But it's anything but clear to me and I don't read it that way. There are no notes that mention 16/9 interpolation anywhare -- only 4/3. Also, after doing a huge number of discs in testing, the only commercial sources I've ever found that was 1440 were 4:3.

Not that it means or proves anything, but a 1920 x 1080p 16:9 source resized to 1440 x 1080p ("anamorphic") and encoded with --sar 4:3 plays undistorted on my SONY standalone.

720x480p@23.976 is valid only as a secondary stream (so it can match the HD primary's framerate) -- not as a primary stream.
I can only go by what I read in the spec -- and unfortunately it seems unclear to me. I guess it could be that since the 1440x1080 source always has a SAR of 4:3, that when it is interpolated it is "corrected" to the 1920x1080 display's 16:9 format. But even according to the link you used, the DAR is always 16:9. Then I have to ask why there is no 16/9 interpolation note anywhere?
I'd like to argue the point one way or the other -- but I've just reviewed it and right now I can't seem to make heads-or-tails of it, and I've always assumed that 1440x1080 implied 4:3. Maybe it'll make more sense to me if I look again tomorrow.
On the other hand this is all an academic exercise as far as BD-RB is concerned anyway -- BD Rebuilder doesn't change the resolution or the aspect ratio (unless you have the conversions implicitly selected in SETUP), so what goes in should come out, regardless of whether it is "legal". I'll go back and check to be sure for 1440, though.

1. What resolution is your source?
2. Is the source an original commercial blu-ray disc (that hasn't been preprocessed)?

Further down in that link (para 1.3) (http://forum.doom9.org/showthread.php?t=154533) there is an indication.

Question is perhaps how does BD-RB resize a 1440x1080 source if 'resize to 720' is selected in the SETUP: if it resizes to 1280x720 and sets explicitely --sar 1:1 I would assume that the encode will play correctly. If it does not explicitely set the --sar but leaves it untouched (4:3) the playback will probably be anamorphic distorted. Hmm... it makes sense that if the SAR is 4:3 and DAR is 16:9 that a 1440 horizontal size would be displayed as 1920 (1.333 * 1440). That would dispel my belief that it's supposed to always be 4:3. But then what happens with a 4:3 source? I need to go back and find my some of my HD 4:3 sources.
I'm going to run a couple of tests and see what happens if I encode a 4:3 source with SAR at 4:3 (which it has to be) to 1440x1080 and set the 4:3 flag.
You ever have days when your thought processes just don't seem to work right? Maybe it's the cast on my leg...
I'll also look at the code and see what SAR I use when reencoding a 1440 source to 720. But more than likely the issue is the AVISYNTH resizing filter -- I may not be taking the 1440's 4:3 SAR into consideration.
[Edit] On second thought. The resize filter shouldn't have to do anything special if the DAR was 16:9. A simple resize to 1280x720 should work. Ugghh

Yep, that's why I deleted the second part of my original post while you already replied.....

@jdobbs, you something misunderstand while reading specs 1440x1080 can only be 16:9 and not 4:3. Square pixels for 1440x1080 are illegal completely. 1440x1080 uses extended SAR information, this means you need to use --sar 4:3 to meet specs. Btw i checked with verifier and it's compatible. 1440x1080 is here because anamorphic encoding from HD cams.
Btw if you need 4:3, you need to leterbox source (left/right)
from spec:
In case of 1440x1080 with aspect_ratio_idc set to 255(Extended_SAR), aspect ratio shall be indicated
by sar_width and sar_height. sar_width shall be set to 4 and sar_height shall be set to 3, respectively

Yes, the only legal way to resize a 1440x1080 source (at this resolution legal SAR is 4:3 only, legal DAR is 16:9 only) to 720 is 1280x720 with --sar 1:1.

1. 1920 x 1080 but the movie is 2.35 : 1
2. Yes. The A Team. Only ripped to hard drive.

from spec: Cool. Thanks. The more I looked at it the more I realized I had it ass-backwards.
